Line an 8x8-inch tin with baking paper. It's helpful to leave a bit hanging over each edge so you can just lift out the traybake later.
Add the desiccated coconut and jelly powder to a bowl and mix well. Then stir in the condensed milk. Make sure to mix it well so everything is combined properly.
Press the mixture evenly into your lined tin.
Melt the chocolate and spread it over the raspberry coconut mixture in the tin. While the chocolate is still wet, sprinkle the freeze-dried raspberry pieces on top.
Place the traybake in the fridge for about 1 hour until the chocolate has hardened. Then just cut it into slices (using a warm knife to prevent cracking) and enjoy!
